I have been testing the 'move' and the test results are excellent. For me I flex the knees quite a bit (Knudson) and knock the knees for a reverse k feel. From that position the knavel thing seems to be linear back and linear on the forward swing which seems to be the perfect govenor for the amount of hip turn back and through. It seems like a half swing and I believe it to be my best power place. Interesting note: In Palmer's book from the 1980's he said that the difference between a half swing and a full swing was about ten yards so pretty much why bother if you can't handle that parallel place.
